Hitachi HM62V16256C
The Hitachi HM62V16256C Series is 4-Mbit static RAM organized 262,144-word × 16-bit. It offers low power standby power dissipation; therefore, it is suitable for battery backup systems.DESCRIPTION
HM62V16256C Series has realized higher density, higher performance and low power consumption by employing CMOS process technology (6-transistor memory cell). It is packaged in standard 44-pin plastic TSOPII.FEATURES
